The new FOCUS harmonic scalpel offers a safe and effective alternative for thyroid surgery, significantly reducing operative time compared to the HARMONIC ACE device.

Area of Science:

  • Surgical Technology
  • Endocrine Surgery
  • Minimally Invasive Surgery

Background:

  • Previous harmonic scalpel devices for thyroid surgery were noted as large and cumbersome.
  • A new, improved harmonic scalpel (FOCUS) became available in 2008.

Purpose of the Study:

  • To compare the efficacy and safety of the new FOCUS harmonic scalpel against the previous HARMONIC ACE device.
  • Evaluate outcomes of total thyroidectomy using both devices.

Main Methods:

  • A prospective randomized study involving 90 patients undergoing total thyroidectomy.
  • Patients were divided into two groups: FOCUS (n=45) and HARMONIC ACE (n=45).

Main Results:

  • No significant differences in patient demographics, gland characteristics, or postoperative outcomes were observed.

  • The mean operative time was significantly reduced with the FOCUS device (63 min) compared to HARMONIC ACE (76 min).

    • Conclusions:

    • The new FOCUS harmonic scalpel is a safe and effective surgical tool for thyroidectomy.
    • Its improved design enhances delicate tissue handling and dissection capabilities.
    • The device leads to a decrease in operative time, benefiting surgeons and potentially patients.
